Re: Fastest way to flash CM3+ for Production

Plugging in uSD or USB cards still takes time & effort, so how would waiting 10 minutes for the device to install be better or worse than 10 minutes for it to install from a different method? As I have explained before. I am not looking to shrink the time it takes to flash a eMMC card. I am looking...

Re: Fastest way to flash CM3+ for Production

I think you should re-read my OP. I am not looking to have anyone connect it to a PC. That way takes far to long, and it would tie up a person sitting there waiting for it to finish. The better method would be to boot from uSD or USB Stick and have that flash the eMMC.

Re: Fastest way to flash CM3+ for Production

I understand the size has a role to play. However even if one were to shrink the size down to 1G that is still going to take ~8-12 minutes to flash. We have been using the NanoPi NEO Air, which we are able to boot from uSD, and a script runs which then copy's the image to eMMC. This is good because ...

Re: Fastest way to flash CM3+ for Production

Thanks, but this is not the issue i am referring to.
I need to (as fast as possible) install the OS onto 100 new CM3+ modules. Plugging each one into a PC and flashing them individually takes far to long.

Fastest way to flash CM3+ for Production

Started to use the CM3+. My focus right now is learning how I will manage flashing the eMMC for production as fast as possible. I installed raspbian-lite and then updated and configured everything the way we need it. Using rpiboot, and Win32DiskImager to read the eMMC and save it on the pc. This all...

Re: STICKY: Is CM3 compatbile with the CM1 development board?

Just like to throw this out, if this is wrong to do here feel free to delete this post. I recently bought this Dev board on Amazon. I have been using the new Raspberry Pi Compute Module M3+ 8 GB module in it and it works great. I only share this because I think its more handy that the stock one RPI ...

Where is the default .dts file ?
I thought I would see it here:

Or am I looking in the wrong spot ?

RPI-COMPUTE3-KIT

Just curious if there might be 2 flavors of the new kit.
I thought it would be nice to also have a baseboard for the CM3x that had the all the same hardware on it as say one of the current RPI boards, such as multiple USB ports, Ethernet connector, and the same I/O header.

Re: WiFI AP with Webserver to configure wifi

I want the device to read some sensor data and put that information to our servers. This is why I need them to set it up for their own WiFi.

WiFI AP with Webserver to configure wifi

I was wondering should I design a headless device to be sold using RPI3 how would I allow the user to set the wi-fi to connect to their own network since they wont have access to the terminal or a monitor. I thought that it would be nice on boot to check a local file to see if the user has set up th...

Re: Pi Zero Temp Spec ?

In my experience manufacturers specify operating and storage temp specs for their devices. Take it or leave it. I have never seen a board manufacurer publish a spec that lists all the temp specs of all the components on their board. Often you are lucky to even find out what iz on the board. The ras...

Whilst officially it's lower limit is -40 (AFAIK) it may be that some of the high altitude balloon guys or penguin monitor guys may have seen temperatures lower than that in real life.

I mean the part with the narrowest range. I.E. -20 to +85 is a narrower range than -40 to +85. But what if one part had -20 to +85 and another had -10 to +120? Then -10 would be the minimum and +85 the maximum. Not determined by the range of a single part. I get what your saying, however I pretty s...

Re: Pi Zero Temp Spec ?

Whilst -40 to +85 is the published temp range, it should be noted that the chip can actually run at MUCH higher temperatures than that. During development the chips are tested in ovens at well over 100 to determine lifetimes and the like. The chip itself, it it detects itself overheating internally...
